Abstract

The invention relates to a water-soluble high-strength high-elasticity putty paint and a preparation method thereof. The water-soluble high-strength high-elasticity putty paint comprises a component A and a component B in a weight ratio of 1: (0.8-1.2), wherein the component A is putty powder, and the component B comprises, in parts by weight, 400-500 parts of elastic resin, 60-100 parts of curing agent, 5-50 parts of tackifier, 5-50 parts of water repellent agent, 50-100 parts of diluent and 25-100 parts of foamed filaments. The putty paint prepared by rationally adjusting the composition and proportions of various raw materials is good in adhesion which is greater than or equal to 2MPa, high in elongation at break and thus capable of extending by 3-4 times, excellent in waterproofness and capable of resisting weather for 15 years, extra excellent in waterproofness and alkali resistance, exceeding 1000hr, respectively, and also environment-friendly and pollution-free; and the formed coating is thick to feel, soft in luster and even in chroma.

Description

technical field [0001] The invention relates to a putty paint, in particular to a water-soluble high-strength and high-elasticity putty paint and a preparation method thereof. Background technique [0002] With the deterioration of the global environment and the strengthening of the energy crisis, people's awareness of energy conservation and environmental protection has gradually increased, so countries all over the world are researching energy-saving and environment-friendly putty paints. The materials used to decorate the wall are imitation porcelain paint and latex paint. The general imitation porcelain paint is not water-resistant, has poor hardness, is easy to powder, and is easy to age. The hardness of the better imitation porcelain tempered paint is still high. Yes, but the washing resistance is poor and the color is single. In addition, the imitation porcelain coating has relatively high requirements during the construction process. The construction methods of polyu...
